What happens when glucose is dissolved in water?
Glucose dissolves in water because polar water molecules attach to the glucose molecules. When a glucose molecule (centre) is placed into water the negatively charged oxygen ions (red) attract and surround the positively charged O-H (hydroxyl- ) groups in glucose, forming hydrogen bonds (white).
What happens when glucose reacts with water?
Due to the dipole moment of water, glucose form hydrogen bond with water and hydrogen enthalpy of glucose is sufficient to make it soluble in water (36) . The glucose molecule converts from solid to the aqueous form as: C 6 H 12 O 6 +H 2 O → C 6 H 12 O 6 (aq). …
How do you find major species present when dissolved in water?
Major Species: For example, if you were to dissolve table salt in water, the major species would be Na+, Cl-, and H2O. The same concept applies to acids and bases – if you were to dissolve HCl in water, the major species would be H+, Cl-, and H2O.

How do you identify dissolution reactions?
Identifying a Dissolution Reaction
- Step 1: Look for a single compound as the reactant.
- Step 2: Look for two or more ions as the product.
- Step 3: Double check all the other answer choices to make sure you didn't miss anything.
What is the example of dissolution reaction?
For example, a mixture of insoluble hematite and elemental iron, when mixed in phosphoric acid, reduces hematite first into wüstite (FeO) by the reaction given in Eqs. (7.1) and (7.6), and then dissolves the resulting FeO in the acidic solution to form phosphates of Fe.
Does ethanol dissolve in water?
Substances composed of small polar molecules, such as acetone and ethanol, are usually soluble in water.

When glucose reacts with br2 water the major product formed is?
Gluconic acid When glucose react with Bromine water, then it undergoes oxidation reaction to form Gluconic acid as a product.
What does glucose dissolve into?
WaterAcetic acid Glucose/Soluble in
How do you find the major species present?
Major Species: For example, if you were to dissolve table salt in water, the major species would be Na+, Cl-, and H2O. The same concept applies to acids and bases – if you were to dissolve HCl in water, the major species would be H+, Cl-, and H2O.
How do you identify major and minor species in chemistry?
The reactants and products of these are the species in solution. Because reactant-favoured reactions have small equilibrium constants, the reactants are major species. The products are minor species.
What is the name of CH3CN?
AcetonitrileAcetonitrile / IUPAC ID
What happens when compounds dissolve in water?
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process represents a physical change known as dissociation.
What happens during dissolution?
Dissolution is the process where a solute in gaseous, liquid, or solid phase dissolves in a solvent to form a solution. Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature.
What is dissolution in water?
Dissolution is the process where a solute in gaseous, liquid, or solid phase dissolves in a solvent to form a solution. Solubility. Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature.
Is isopropyl alcohol soluble in water?
As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms….Isopropyl alcohol.

Why is propanol soluble in water?
This is due to the hydroxyl group that can form hydrogen bonds with water molecules in the alcohol. Alcohols are highly soluble with a smaller hydrocarbon chain. Solubility in water decreases as the length of the hydrocarbon chain increases.
What kind of compounds are most soluble in water?
Among given compounds, ethylene glycol ( HO−CH2−CH2−OH ) is the most soluble in water. Ethylene glycol has two hydroxy groups both of which form hydrogen bonds with water. Greater is the number of hydrogen bonds, greater is the extent of hydrogen bonding and greater is the solubility in water.
Which of the following will be the most soluble in water?
Methanol would have the highest solubility in water since it contains the smallest hydrophobic portion in its…
When glucose reacts with bromine water the major product is a gluconic acid B saccharic acid C sorbitol D galactose?
bromine water is mild oxidizing agent and oxidation of glucose with bromine water to gluconic acid shows that the carbonyl group in glucose is aldehyde group.
When glucose reacts with br2 water the main product is a acetic acid B saccharic acid C glyceraldehyde D-gluconic acid?
Saccharic acid is obtained when aldehyde and alcoholic groups on glucose are oxidized to COOH this process takes place when we use a strong oxidizing agent like nitric acid. Thus option (D) is correct.
Is glucose soluble in alcohol?
Chemical properties. Glucose forms white or colorless solids that are highly soluble in water and acetic acid but poorly soluble in methanol and ethanol.
How do you determine Major and minor species?
The reactants and products of these are the species in solution. Because reactant-favoured reactions have small equilibrium constants, the reactants are major species. The products are minor species. Acids or bases that have a charge (HCO2– or NH4+ for example) will be dissolved as a salt (such HCO2Na or NH4Cl).
How do you identify the major product?
Applying Markovnikov Rule Hence according to Markovnikov Rule, when hydrogen is added to the carbon with more hydrogen, we will get the major product. This means that when hydrogen is added to carbon-1, which has more hydrogen, and bromine is added to carbon-2, the product 2-bromopropane will be the major product.
